Example of HotStart function
Arc-force dy-
To obtain optimum welding results, it will sometimes be necessary to adjust the
namic
arc-force dynamic.
Setting range: 0 - 100 (corresponds to 0 - 200 A current increase)
Operating principle:
At the moment of droplet transfer or in the event of a short circuit, the amper-
age is briefly increased in order to obtain a stable arc.
If the rod electrode threatens to sink into the weld pool, this measure prevents
the weld pool solidifying, as well as preventing a prolonged short-circuit of the
arc. This largely prevents the rod electrode from sticking.
Setting the arc-force dynamic:
1
Turn the adjusting dial until the desired value is reached
-
power source is ready for welding
TransPocket 150 to 160 A
TransPocket 180 to 200 A
= 100 A starting current = function deactivated
= 80 A starting current = SoftStart
= 135 A starting current = HotStart
= 160 A starting current on TransPocket 150 = HotStart, maximum
current limit is reached!
= 200 A starting current on TransPocket 180 = HotStart
0,5 s

Press the setting value button until

the arc-force dynamic indicator lights up
Features of SoftStart function:
-
Reduced pore formation with cer-
tain electrode types
Features of HotStart function:
-
Improved ignition properties, even
when using electrodes with poor
ignition properties
-
Better fusion of the base material
during the start-up phase, meaning
fewer cold-shut defects
-
Largely prevents slag inclusions
